7. Avoid high heels. They can shift your center of gravity and strain your lower back. Stick to a one-inch heel. If you have to go higher, bring along a pair of low-heeled shoes and slip into them if you become uncomfortable.
8. Stash the skinny jeans. Clothing so tight that it interferes with bending, sitting, or walking can aggravate back pain.
9. Lighten your wallet. Sitting on an overstuffed wallet may cause discomfort and back pain. If you’re going to be sitting for a prolonged period -- while driving, for example, take your wallet out of your back pocket.
10. Pick the right handbag or briefcase. Buy a bag or briefcase with a wide, adjustable strap that’s long enough to reach over your head. A messenger bag (like the ones bike messengers wear) is made to wear this way. Having the strap on the opposite shoulder of the bag distributes the weight more evenly and helps keep your shoulders even and your back pain-free. When carrying a heavy bag or case without straps, switch hands frequently to avoid putting all the stress on one side of the body. To lighten the load, periodically purge bags, cases, backpacks, and other carriers of things you don't need.
11. Forget about back braces. Various back supports are available, from elastic bands to special corsets. They can be helpful after certain kinds of surgery, but there is not much evidence that they help treat chronic back pain.
